Which material sounds better for speakers construction? Wood, Ply or MDF?

@ebm You better believe it they ring like a bell! No matter the bracing. You can't just knock on them as a test. You need a tone generator and vibration measuring tools. 

Take a look at Stereophile, every review of Magico omits this test, but all other speakers have it. There's a reason for it. 

ebm@  you right, The Magico , YG is not stupid, The harder material
get less  vibration , The harder wood, bamboo also better them MDF.
In reality  good braced  MDF is also good enough, The conclusion
if you  gonna spend more money--- best choice -aluminum , next
solid wood  and   last -MDF 

ho ho ho..ebm doesn’t think his speakers ring.  This is very important!   😉
